R is a language and environment for statistical computing and graphics; you can think of it as a combination of a statistics package and a programming language.
R is completely free; you don’t have to pay for it, and you can make any modifications you want to it
R runs on Windows, MacOS, Linux, and many Unix variants
R is not supported by any commercial enterprise, but it has a very active development community, and there are companies that offer training courses etc.. The manuals are complete and there are many books on it.
R has an enormous number of standard and cutting-edge statistical functions built in, a wide variety of (free) add-in packages that add even more functions, and you can extend it further. Every standard statistical analysis can be done in R.
R is mostly command-line driven (although various graphical interfaces have been developed); this makes it harder to use but allows flexibility and documentation and repetition of analyses.

People use R to analyze data in the fields (alphabetical order) of:

agriculture
astrophysics
climatology
ecology and environmental science
econometrics
electrical engineering
finance
genetics and genomics
geography
psychology
social sciences

and many more.

There are 3 modules in the folder. Put them in modules/R/. This package works in cli and graphs are x-based, so they should be ok for all the DE's of Porteus.

Enjoy Science & Statistics!
